摘要
对可应用于神光Ⅱ精密化项目的变角度薄膜衰减器进行了理论分析、数值计算,在小激光装置上进行了闭环自动衰减控制实验.模拟实验证实了该衰减器具有精密连续可调、大口径、高能量负载、高光束质量的特点,这是其它光学衰减器难以做到的.
Abstract
Theoretic analysis and numerical computation on film attenuator of variable angle are studied. The attenuator is ready to be used in SHENGUANG Ⅱ precision project. The characteristics of precisionly continuous adjust, large optical aperture, high energy loading and high beam quality are demonstrated in simulation experiment. Other optical attenuators can not provide with these characteristics solely.
